Here I get an error "The type org.eclipse.jdt.core.refactoring.descriptors.RenameJavaElementDescriptor cannot be resolved. It is indirectly referenced from required .class files".
It looks weird. I thought it should be in the same jar. Help says that RenameJavaElementDescriptors declared in the package org.eclipse.jdt.core.refactoring.descriptors. But I cannot find this package. Where I can find it? Eclipse 3.7
